/**
 * Patches pglite-prisma-adapter to fix Bytes column handling.
 *
 * The adapter's parsePgBytes returns Uint8Array, which serializes as a JSON
 * object {"0":104,"1":101,...} across the JS-WASM boundary to the Prisma
 * query engine. The engine expects either a plain number[] or a base64 string.
 *
 * Fix: replace Uint8Array.from with Array.from so the result is a plain number[].
 *
 * Upstream issue: https://github.com/nicksrandall/pglite-prisma-adapter
